Thanks for the feedback. Sonarr semi works but requires some fixed shares for now. I'll release it when there's no more reboot and uninstall bugs. To pair it with nzbget it needs the public ip, not localhost and the category is series instead of tv. Create a public P2P and Multimedia/TV share before installing. Sonarr (docker) maps this to a local /downloads and a /tv folder. I'll explain in more detail when it's more dummy proof.
Scripted user management is painful but one of my main priorities.. now everything is root .
Manually over ssh it's more flexible but I'm targetting the non-ssh way.
All that said... let's keep this topic to nzbget.. please wait for my sonarr release in another topic.
